MOTOR-OYCLE-SEAT BACK.

Specification of Letters'Patent. Patented New. 21, 1916.

Application fired June 24, 1916'. Serial No. 105,522.

To all whom it may concern Be it known that I, CHARLES A. HonHN, acitizen ofthe United" States, residing at lVilkinsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in lVlotor-Cyele-Seat Backs, of which the foll'owingis a specification, reference being had therein to the accompanyingdrawing.

This invention relates to backs which are adapted to be used especiallywith motorcycles and bicycles and has for its principal object theproduction'of a back which may be 'efficiently and easily attached to ordetached from a seat.

Another object of this invention'is in the production of a back providedwith a supporting frame which is formed from a single strand of wire.

Another object of this invention is in the production of a back providedwith a body portion formed from a single sheet of metal and adapted tobe bent in such a manner as to engage the supporting frame.

Still a further object of this invention is in the production of asimple and efficient clip which is formed from a single sheet of metaland is adapted to be bent in such'a manner as to hold the body plate inengage ment with. the supporting frame.

With these and other objects in view, this invention consists of certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawings, Figure lis a side elevation of a motor-cycle seatshowing the back attached thereto. Fig. 2 is a front elevation of thesupporting plates of the motor-cycle seat showing the same partly insection and carrying the device. Fig. 3 is a rear elevation ofthe deviceshowing the same stripped of the customary padding. Fig. at is a sectiontaken on the line 1- 1 of Fig. 2. Fig. 5 is av section taken on the line55 of Fig. 3. Fig. dis a fragmentary bottom plan view of the deviceshowing the eye.

By referring to the drawings, by numerals, it will be seen that 1designates a motorcycle seat which is carried by the supporting plates2. These supporting plates are pro-' 'vided with apertures so as toreceive the bolts 3, which are held in engagement with the plate 2 bymeans of the nuts 4. These plates 2 are adapted to support the back 5.

Thisba'ck 5 comprisesthe body portion 6 which is adapted to be struckfrom a single sheet of metal and also to be bent so as to tothesemi-circular portion 9, as is clearly shown in Fig. 1. After the yeshave been formed the resilient wire is bent so as to form the supportingarms 11. These arm's 11 extend in substantially the same thesemi-circular portion 9. I

The ends of the arms 11 extend a space plane as distance from theuppermost portion of the semi-circular portion 9 as is shown-in Fig.These arms are held in engagement with the body 6 by means of the clip12 by means 7 of the rivet 13. This clip 12 is formed of a sheet ofmetal substantially rectangular in shape and is bent so as to form thebody portion 1st and is bent so as to form the sockets 15 and is thenbent so as to form the lips 16. referring to Fig. 5. that the lips 16and the body 14: are provided with apertures so as to receive the rivet13.

When this device is in operation, it is placed in engagement with thelower face of the supporting plate 2, as is shown in Fig. 2, and is heldthereon by means of a bolt and nut 3 and Land. it will also'be seen thatbecause of the fact that the supporting frame 8 is formed from resilientwire that parted tothe back 5. Of course, this back It should beunderstood, by

a certain amount of resiliency will be 'im 5 is provided with thepadding17 which is held in place by the leather covering 18 as is clearly shownin Fig. 4.

From the above description, it will be seen 7 that a very simple andeflicient back has been produced which may be especially used uponamotor-cycle seat and of course, may also be useduponbicycle seats,tricycle seats and the like. It willalso be noted that the device isconstructed'so as to be formed of two major portions. One of these majorportions, the supporting frame, is adapted to be formed from a singlestrand of re silient wire and the other portion, the body,-

to be struck from a single sheet of metal,

whereby thedevice may be manufactured with the least possible expense.

What is claimed is:

1. A device of the class described comprising a supporting frame, saidsupporting frame adapted to be bent from a single strand of resilientwire so as to form a semicircular body portion, said body portionterminating in eyes, said eyes adapted to extend at right angles to theplane of said body portion, said eyes terminating in arms, said armsextending parallel to one another and in the same direction with thebody portion, said frame adapted to be supported upon a seat wherebybecause of the resilient nature a of the wire, the back will havesuflicient give, and means for holding said supporting frame upon aseat.

2. In a device of the class described, the combination of a supportingframe with a body portion, said body portion adapted to be struck from asingle sheet of metal and provided with a channel extending around itscircular periphery, said channel adapted to receive said supportingframe, said supporting frame adapted to be formed from a single strandof resilient wire and bent so as to form a semi-circular body, said bodyterminating in eyes extending at right angles thereto, said eyesterminating in arms, said arms ext-ending parallel to one another and inthe same direction with said semi-circular body whereby because of theresilient wire sufficient give will be imparted to the device, and meansprovided for attaching said supporting frame tosaid body portion.

3. In a device of the class described, the

combination of a supporting frame with a body portion, said body portionadapted to be struck from a single sheet of metal and provided with achannel extending around its circular periphery, said channel adapted toreceive said supporting frame, said supporting frame adapted to beformed from a single strand of resilient wire and bent so as v to form asemi-circular body, said body ter-V CHARLES a HOEHN;
